VAPOR-BURNER.

SPECIFICATION .forming part of Letters Patent No.v 329A81, dated November 3,1885.

Application filed April 21, reet.

T tZZ whom it may concern:

Be it known that I, EDMOND C. PEOKof Chicago, in the county of Cook andV State of Illinois, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare that the following is a full, clear, andexact description .of the invention, which will enable Others skilled in the art to which it appertains to make and use the same, referentel being had to the accompanying drawings, and to letters of reference marked thereon,.whichform a part of this specification.

The object ofniy invention is to provide va new and improved vapor-burner which thoroughly -mixes the water and oil vapors generated therein, which is so constructed that it protects the heretofore exposed parts fromthe great heat to which they would otherwise be exposed, and in which the oil receiving, vaporizing, and vapormixing chamber is so constructed that the oil cannot escape into the water-vaporizing chamber connected therewith, and so that the vaporizing ofthe oil and the mixing of the same with the water-vapor are greatly facilitated, substantially as hereinafter described, and as illustrated in the dra-W- ings, in which- Figure I is a longitudinal vertical section through the center of my improved vaporburner. Fig. 2 is a plan view of the under side of the oil-vaporizing and vapor-mixing chamber, and Fig. 3 is a plan view of the drippan.

In the drawings, A represents a drip-pan having a central circular opening, a, which has a vertical wall, a', rising from itszcircumference, to prevent the escape from the pan of the oil that may flow into it, as will be hereinafter more fully explained. This pan A is so constructed that its sides and bottom slope in toward the longitudinal center, thus massing the oil around the wall a', arising from the edges of the central opening. The incline of the bottom of the pan is not continuous, but is broken by a transverse horizontal plane surface or step, a2, the purpose of which will be explained further on. Projecting from the edges of the drip-pan is a horizontal flange, which forms a shoulder, on which the outer vertical casing, B, rests and is supported.

Sci-inl No. 162,893. (No model.)

Extending centrally and vertically up, through the opening a of the drip-pan is the steam or water-vaporizing chamber C. This chamber C tapers towardl its lower end, where a watersupply pipe, b, is connected to it. Its upper end is stepped to a less .diameterthus forming a shoulder-,and the circumference of this stepped portion is screw-threaded, so as to screw into and connect with the upper part or cap, c, of chamber C. Depending and flaring outward from the lower edges of cap c is the bell-shaped shield d, which is designed to protect the walls of chamber G from the. damaging effects of theintense heat generated by the Icombustionwithin casing B. The circumference of cap c contiguous to its closed topv is screw-threaded, so as to screw into the apertures in the raised center of the.bottom ofthe oil receiving and-vaporizing and vapormixing chamber D. c is a tube, e, which affords an outlet into the mixing-chamber D -for the water-vapor generated in chamber C. This tube e is provided with a disk-shaped cap, c, which is adjustable on the screw-threaded upper end of a vertical post secured in the bore of said tube in such manner as not to obstruct the exit of the steam or watervapor., The object of cap e is to obstruct the mouth of tube c, so that the steam will issue therefrom with such force as to thoroughly commingle with the oil-vapor generated in chamber D.

Projecting verticallyvup through aslot made in the bottom of the drip-pan, and open to and made radially from the opening a, is the oilsupply pipe E. This pipe E passes up through the bottom of the chamber D, and terminates a slight distance above the same. The side walls .of the oil receiving and vaporizing and vapor-mixing chamber D, adjacent to the bottom thereof, are sloped or inclined inward toward the raised central part, and arranged (preferably) on alongitudinal central line near the ends of this chamber D are the hollow bosses ff. These bosses f project downward from the inclined portions of the sides of said chamber D, and the inner or upper surfaces of their floors are raised a little above that surrounding the base of the raised center of chamber D, thus forming a gutter around the said raised center, which must be filled with Oil be- In the head of this cap IOO fore the oil can llow over the floorsof the bosses fand down through the eduction-pipes F F into the drip-pan.' These eduction-pipes F pass vertically'downward from the bosses f, (into a hole in which their upper ends are screwed,) and are provided at their lower ends with T-couplings g g, which rest upon the plane surfaces a2 of the drip-pan A. `Connected to and extending laterally from the hori zontal arms of the couplings g are the jets G, which have orifices in their upper sides near their extremities. In the vertical arm of one or both of the couplings g, Iplace a valve, H, so that if the heat generated by the supply from both eduction-pipes of gas is too great one cany bey closed.

The top of the mixingchamber- D is closed and renderedair-tight by a suitableplate-made integrant with the side walls., Secured to vand projecting from the topy of said chamber D is a flat ring-shaped deflector, J, whoseedges extendout to or slightly beyondthe vertical plane of thev casing, B.

In operating my Vapor-burner, I first turn on the oil,.by means of a, suitablefvalve inthe oil-supply pipe, which*V rises into and fills the gutter in the bottom ot' the chamber D, sur rounding the raised center thereof, and then` flows ontothe floor ofthebossesfdown through the educlion-pipes andjetsand into the drip pan. When a sufficient quantity of oil has owed into thedrip-panf, itA is. ignited.` The heat created by the combustion of the oil inthe pan soon vaporizes the water in chamber C and the oil in chamber D. The water-vapor orl steam rises through tube e, and. is deflected` by cap e int-o the oil-vaporizingchamber,an d', commingling with the oil-vapor, forms a gas, which passes dow n through the eduction pipes,l out through the jets-into the combustiomehamh ber formedI above the, drip-pan, within the" l casing B, and below the oil-vaporizing'cham.-

ber D; Asthis gasissues fromv the jets, it is.

ignited by the Haines' arising from the remain f ing oil in the drip-pan, andy burns with` an intense heat. When the oil in chamber D' begins to vaporize, it ceases to flow: down 'through the ed-uctionpipes, andthe oil, at

any .time after it commences to vaporize, and, in fact, at any time after the appa.

ratusis set in operation, will not. more than ill the gutter surroundingy the `raised center of the mixing chamber, and thus a smaller quantity of oil is always in this chamber than in the chamber of other vapor-burners, a-nd consequently it vaporizes sooner. The reason the central portion of the mixingchamber, to which the escape -tube of the watervaporizing chamber; is connected, is raised is to prevent the oil from flowing into the water-chamber. rEhe sides of chamber D are inclined inward, so that the oil may gravitate toward the raised central part. Thus, as the vapors arise from theheated oil, they will bein close proximity to the escaping jet of steam, andthus facilitate the commingling of the two. Another feature of these inclined sides is, that they deect the Iiames and heat out between the upper edges of the casing B and the deflector Y.

WhatI claim as new, and desire to secure by Letters Patent, is- 1. The combination, in a vapor burner, with a. water-vaporizing chamber having a suitable water-supply pipe connected thereto, of an oil receiving and vaporizing and vapor-mix` ing chamber having an oil-supply pipe con` nected therewith, having the-lower portion of itsV side walls adjacentV to its bottom incl-ined inward, and having hollow bosses extending downward fromthe inclined side walls, to which the eduction-pipes are connected.r

2. Ina vaporburner, the combination,with a. water-vaporizing chamber, water-supply pipe connected thereto, and escape-tube, of

an oil receiving and* vaporzing and vapormixing chamber having a raised central por-v tion, the central portion of its bottom to which saidwater-vaporizing chamber is connectedv v raised abovethe plane of the surrounding bot- .tomthereto,and the eduction-pipes leading therefrom. l

" 3. In a vapor-burner, the combination, with a drip-pan, A, casing B, and chamber`D` of a vwatervaporizing chamber and shield d, surrounding said chamber, asand for the purpose set forth.

4l. In avaporburne13 the combination,witl1 a water-vaporizing chamber, C, tube e, and

cape,.of the mixing-chamber D and edu.ction pi-.pes F' F.

In*4 testimony that I claim the foregoing as XOO my own I hereunto affix m'ysignaturein pres` ence of two witnesses.
